AUTOMATIC llClAt'tKEIt.l

To all whom @'15 may conce/m Be it known that T, CLARENCE C. COX, acitizen of the United States, residing at Vigo, in the county of Rossand State of Chio, have invented new and useful Improvements inAutomatic Markers, of which the following is a specification.

This invention relates to planters and more particularly to markerattachments for this type of agricultural impleinent.

@ne of the principal objects of the invention is to provide a markerwhich may be readily mounted upon the ordinary type of corn planter andbe conveniently operated so that the marker disk or member may be easilyraised when turning at the end of the row and which also may be operatedfrom either side of the machine.

A further object of the invention is the ff provision of a device ofthis character which embodies a safetv appliance adapted to prevent themarker rod from breaking when the marker member strikes an immovableobject.

il still further object of the invention will appear as the followingspecific description is read in connection with the acconipanyingdrawings which form a part of this invention in which Figure 1 is a topplan view showing the device attached on an ordinary corn planter. l?ig. 2 is a rear elevation. Fig. 3 a detail side elevation of the machineshowing the alternative position of the lever in dotted lines. Fig. etis a detail section through the marker rod.

Referring more particularly to the drawings, 1 represents an ordinarycorn plantel' frame which is supported upon the wheel axle 2, the lattermember carrying the usual covering and supporting wheels 3 secured tothe rear member e: of the frame and to an intermediate cross brace 5 aresuitable bearings G in which a shaft 7 is journaled. This shaft has itsrear end turned at right angles as shown at S and its terminal. endbifurcated as shown at 9 to receive the pivoting end 10 of a stub shaft11. The stub shaft 11 is entered into the marker rod 12 which is in theform of a pipe of any suitable cross sectional contour and carries uponits outer end a suitable marking disk 13. The shaft 7 is also journaledadjacent its right angular end in a bearing 111-. which is carried by aframe 15 secured to the main frame 1 and ySpeccation of Letters Patent.

Patented July 22, 1913. Serial No. 643,722.

having lvertical offset ends so that it will be depressed below the mainframe, These bearings are all reu'iovably mounted upon the planter andthe frame 15 similarly mounted so that the attachment may be readilyremoved or placed upon the frame when desired. Surrounding the shaft 7is a clamp 1G and a similar clamp 17 surrouucs the tubular rod l2 and isconnected to the first clamp by a link or brace rod 1S. This brace rodconnected to the clamp by a frangible pin 18a, for a purpose which willbe hereinafter described.

Journaled upon the shaft 7 `is a bearing member 19 which is heldagainstlongitudinal movement upon the shaft by transverse pins 2Oextending through said shaft. The bearing 19 is provided with alaterally extending nipple in which one end of an operating shaft 21journaled, the opposite end of the shaft being journaled in a bearing 2Qremovably mounted upon the side of the main frame 1 between the legs ofa locking segment 23 also secured to the frame. The end of the shaft 21has secured thereto a lever 241 which carries the usual spring lockingdog 25 operated by the handle and link connection 26 and adapted toengage a notch in the center of the segment 23. The shaft Q1 carries abeveled gear Q7 which meshes with a similar gear Q8 keyed to the shaft 7so that by raising the lever to a position where the .locking dogengages the notch in the segment, the shaft i' will. be given a quarterof a revolution and the marker 13' will. ble raised to aver-ticalposition. By continuing the movement of the lever in the samedirection or to the position shown in dotted lines in Fig. 3, the markermay be positioned upon the opposite side of the machine. The pin 18 hassullicient strength under ordinary circumstances to hold the marker rodin alinement with the extension S. Tf,however, the marker should engagean immovable obj ect, such as a stump or large rock, the pin 18il willbreak and the marker rod will pivot on the extension S, thus preventingthe marker rod from breaking.

Having thus fully described the invention, what I claim is v lncombination, a planter frame, a shaft journaled therein, a pivotedlever, a gear connection between the lever and the shaft whereby theshaft may be positively rotated in either direction, a right angular endupon In testinion)7 whereof I aiix iny signature the shaft, i stub shaftpivoted upon said in presence of two Witnesses.
